    A novel fault location approach for radial power distribution systems
    (Institute of Advanced Engineering and Science, 2022) Hamdouche, Tarek; Bendjeghaba, Omar; Brakta, Noureddine; Ahriche, Aimad
    Power distribution systems (PDS) are increasingly complex and spread over long distances and in different locations. Given their radial configuration, the loads could be inserted at the same distances from the substation. This leads to multiple estimation of fault location (FL) and yields time consuming for iterative FL algorithms. In this article, we provide a novel practical approach to fault localization in order to defeat these limitations. The central idea of the proposed approach is to divide the multilateral distribution system into a possible number of mono-lateral sub systems (MLS) using a proposed communicating sensor. Next, we apply two different fault locator algorithms only to the defective MLS. The first variant of the approach is based on the impedance method, while the second variant is non-parametric used only when there is lack in the line data. To test the proposed technique in practice, we used the IEEE 13 Node test feeder, and a real Algerian PDS. The results obtained clearly show the contribution of the dedicated method for locating faults in the PDS

    A Practical Integrated Fault Location Technique for Radial Power Distribution Systems
    (IEEE, 2019) Hamdouche, Tarek; BENDJEGHABA, Omar; Ahriche, Aimad
    power distribution systems (PDS) are becoming more complex and dispersed at long distances and different locations. With its radial and several laterals configuration, loads could be connected at similar distances from the substation which leads to a multi estimation of fault location and consuming more time for iterative fault location algorithms. In order to overcome those difficulties, a practical integrated fault location method for radial PDS is presented in this paper. The basic idea of the proposed approach is to partition a multi lateral distribution system to possible mono lateral system (MLSs) by a proposed communicant sensor (CS). Then an impedance based algorithm is applied only at the faulty MLS. To examine the whole method in the field, a real PDS from the Algerian distribution grid is used. Experimental results present significant benefits compared to a previous method reported in the literature
